PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL
WARNING: Do not use cruise
control on winding roads, in heavy traffic
or when the road surface is slippery. This
could result in loss of vehicle control,
serious injury or death.
WARNING: When you are going
downhill, your vehicle speed could
increase above the set speed. The
system does not apply the brakes.
To help the system to maintain the set
speed when going downhill, downshift to
a lower gear.
Your vehicle speed could decrease below
the set speed when driving uphill.
Note: The system cancels if your vehicle
speed drops below 10 mph (16 km/h) under
the set speed when driving uphill.
